I believe you should add a couple of reference points into your table.

My Suburban weighs 4,000 pounds (2,800,000 grains). Moving at 1 inch per second (.083 FPS) it has .42 ft-lb of energy.

Using your formula, this gives a "weight energy ratio" of 3,341.

This means that according to you, getting hit by my Suburban at 1 inch per second is 3,341 times more destructive than a .22, and over 10 times more destructive than a .500 S&W Magnum!

I'll have to try it, but I doubt if I'll even notice getting hit by my Suburban at 1 inch per second. On the other hand, I have no intention of being hit by a .22 or a .500 S&W!

I'm an even better example. I weigh 160 pounds (1,120,000 grains) and walk at about 2 MPH (3 FPS). This means that while walking I have 22.3 ft-lb of energy, with a "weight energy ratio" of 7,127! Wow!

Me walking into you means that I'm over 7,000 times more destructive than a .22, and 20 times more destructive than a .500 S&W Magnum! I'm like a super-hero!
